Columbia Pictures has released the full theatrical movie trailer for Year One. The film stars Jack Black and Michael Cera, as a couple of lazy hunter-gatherers who are banished from their primitive village, and set off on an epic journey through the ancient world. Directed by National Lampoon’s Vacation and Groundhog Day helmer Harold Ramis, and written by Office scribes Gene Stupnitsky & Lee Eisenberg (you know, the guys working on the new Ghostbusters script).

I feel like I should be into this a lot more than I am. The movie is being unofficially billed as “this generation’s Life of Brian”, but I’m not impressed with that I’ve seen thus far. I’m a fan of most of the comic cast, a big fan of the director’s earlier work, and the concept has a lot of potential, but I’m not finding many of the jokes particularly funny or clever. It seems like they chose to go for more of a traditional comedy than play with the abundance of possible biblical jokes. Watch the new trailer after the jump and leave your thoughts in the comments below.
